Description

Technical Field

[0001] The invention relates to the technical field of cloth processing, and in particular to a coating device for producing polyester cloth. Background Art

[0002] Polyester is a common polyester fiber. Due to its fineness, high softness, and good breathability, it is widely used in clothing, home textiles and other fields. However, in some special environments, such as sunlight exposure and humidity, the surface of polyester fibers is easily damaged, affecting product performance and appearance. Therefore, polyester surface coating technology came into being. Polyester surface coating is a method of modifying the surface of polyester fibers through coating technology. Common coating materials include polyurethane, fluorocarbon, acrylic, etc., which can be used to coat and modify the surface of polyester fibers to achieve sun protection, waterproofing, antibacterial and other effects. Polyester fabric coating is usually achieved using a coating device.

[0003] Patent publication number CN217491448U discloses a composite fabric gluing device, comprising a backing plate, an unwinding mechanism, a gluing mechanism, and a rewinding mechanism. The unwinding mechanism is located on one side of the backing plate. The gluing mechanism includes a connecting assembly, a material storage box, and a gluing roller. The material storage box is located on the side of the connecting assembly away from the backing plate. The gluing roller is located at the discharge port at the bottom of the material storage box and is rotatably connected to the connecting assembly. The side of the connecting assembly closest to the backing plate is connected to the backing plate. The rewinding mechanism includes a pressure roller and a support roller, both of which are rotatably connected to the backing plate. When the device is in operation, the coating in the material storage box flows through the discharge port onto the gluing roller. The gluing roller rotates under the influence of the fabric and applies the coating to the fabric.

[0004] However, due to the paint's poor fluidity and strong adhesion, the paint on the inner wall of the storage box is prone to drying up. This dried paint falls to the bottom of the storage box and flows into the dispensing port along with the flowing paint. This affects the distance between the dispensing port and the coating roller, causing uneven coating thickness on the roller and, in turn, uneven coating thickness on the fabric, affecting the fabric's quality. Furthermore, if this continues for a long time, the gap between the dispensing port and the coating roller will become clogged, until the paint cannot flow out, causing the coating process to cease. Summary of the Invention

[0005] The present invention provides a coating device for producing polyester cloth, aiming to solve the technical problem in the related art that the coating thickness of the cloth is uneven, which affects the molding quality of the cloth.

[0006] The polyester fabric coating device of the present invention comprises a fabric conveyor, a material storage tank for storing coating material arranged above the fabric conveyor, a debris removal conveyor arranged in the material storage tank, a scraper assembly and a debris storage bent plate;

[0007] The bottom of the material storage tank is provided with an outlet for the paint to flow out and be applied to the surface of the cloth; the material storage tank comprises a front inner wall and a rear inner wall arranged in sequence along the conveying direction of the cloth, and two side inner walls arranged in sequence along the width direction of the cloth and connecting the front inner wall and the rear inner wall; the front inner wall and the rear inner wall both comprise an inwardly concave arc surface;

[0008] The impurity removal conveyor includes two rollers disposed between two arc-shaped surfaces and an endless conveyor belt sleeved on the outer walls of the two rollers; the horizontal conveying direction of the endless conveyor belt is parallel to the conveying direction of the cloth; the scraper assembly includes a scraper disposed on the endless conveyor belt and rotating around an axis in the width direction of the cloth; the scraper is used to rotate synchronously with the drive of the endless conveyor belt to scrape impurities on the front inner wall, the rear inner wall and the side inner wall;

[0009] The impurity storage bent plate is in the shape of a concave arc plate and is arranged between the rear inner wall and the endless conveyor belt along the width direction of the cloth, and is used to scrape off and receive impurities adhered to the scraper.

[0010] In the polyester fabric coating production device of the present invention, a scraper rotates under the drive of a debris removal conveyor, scraping away impurities such as dried paint from the front inner wall, rear inner wall, and side inner wall. It also filters impurities in the reservoir, such as dried paint or fabric debris, to prevent the accumulation of impurities at the bottom of the reservoir. This ensures a uniform distance between the discharge port and the fabric, resulting in a uniform coating thickness on the fabric and ensuring fabric forming quality. Furthermore, the scraper's rotation within the reservoir accelerates the flow of the paint, preventing it from drying out.

[0011] Preferably, there are two scraper assemblies; the two scraper assemblies are centrally symmetrical about the center of the endless conveyor belt; along the width direction of the cloth, one end of the scraper contacts the side inner wall, and the other end of the scraper exceeds the middle position of the storage pool; the scraper and the storage bent plate are both provided with mesh holes.

[0012] By providing two scrapers, problems such as the scraper being too long, causing excessive resistance when rotating in the paint, and the scraper being easily bent or deformed, which would occur if only one scraper were used, can be avoided. Moreover, since the two scrapers scrape away impurities in overlapping areas, the scraping effect of impurities is improved, and areas that are not scraped away are avoided.

[0013] Preferably, the scraper assembly also includes a strip mounting seat provided on the outer surface of the endless conveyor belt along the width direction of the cloth, and the scraper is arranged on the strip mounting seat by rotating around the length direction of the strip mounting seat through a first rotating shaft; a first torsion spring for resetting the scraper is sleeved on the first rotating shaft.

[0014] When the scraper scrapes off firmly adhering impurities, the scraper can rotate relative to the strip mounting seat, that is, the scraper is in flexible contact with the impurities, so that the scraper can continue to rotate driven by the endless conveyor belt, avoiding damage to the scraper and the driving mechanism of the impurity removal conveyor.

[0015] Preferably, the scraper assembly further comprises a limiting groove formed on the surface of the endless conveyor belt and extending to the middle of the endless conveyor belt along the width direction of the cloth, and a push rod assembled in the limiting groove;

[0016] The strip-shaped mounting seat is connected to one end of the push rod located in the middle of the endless conveyor belt by a second rotating shaft, which rotates around an axis perpendicular to the surface of the endless conveyor belt; a second torsion spring is sleeved on the second rotating shaft for resetting the strip-shaped mounting seat; the axis of the second rotating shaft is eccentrically arranged at the rotating end of the strip-shaped mounting seat;

[0017] The scraper contacts one end of the side inner wall and is provided with a rounded corner at the corner away from the feeding position; the end of the push rod located on the side of the annular conveyor belt is inserted into the annular groove on the corresponding side inner wall, and the groove depth at the bottom position of the annular groove is smaller than the groove depth at other positions of the annular groove.

[0018] When the scraper rotates to the bottom of the storage tank, the side end of the scraper deflects toward the feeding position, facilitating the paint in the middle of the storage tank to flow toward the side end, thereby allowing the paint to quickly fill the storage tank, thereby facilitating the coating work of the fabric.

[0019] Preferably, the debris removal conveyor further comprises a debris removal drive motor provided on the outer wall of the storage tank; an end of the debris storage bent plate away from the debris removal drive motor is mounted on the corresponding side inner wall via a spring, and an end of the debris storage bent plate close to the debris removal drive motor is provided with a connecting rod passing through the corresponding side inner wall;

[0020] A circular rotating disk is fixedly sleeved on the output shaft of the impurity removal drive motor, and grooves uniformly distributed along the circumference of the circular rotating disk are provided on the end surface of the circular rotating disk close to the impurity storage bent plate; the end of the connecting rod contacts the end surface of the circular rotating disk.

[0021] The storage bent plate can scrape off impurities adhering to the scraper and temporarily store impurities. As the circular rotating disk rotates continuously, the storage bent plate vibrates back and forth along the width of the fabric, thereby accelerating the downward flow of paint in the storage bent plate.

[0022] Preferably, along the conveying direction of the cloth, a rotating roller is provided at the bottom of the front end of the discharge port for rotating driven by the cloth.

[0023] By arranging the rotating roller, when the cloth passes through the front end of the discharge port, the rotating roller is driven to rotate, so that the paint at this location is in a flowing state, thereby preventing the paint from drying up.

[0024] Preferably, the polyester fabric production coating device further comprises a drying mechanism provided at the tail end of the fabric conveyor, and the drying mechanism is used for drying the fabric coated with the coating.

[0025] Preferably, the polyester fabric production coating device further includes a feed pipe, and the outlet of the feed pipe is arranged above the miscellaneous storage bent plate.

[0026] Preferably, the material conveyor includes a bracket, a conveying assembly provided on the bracket for conveying the material, and an adjustable support mechanism located on both sides of the conveying assembly; the adjustable support mechanism includes a first support column vertically provided on the bracket, a sleeve adjustably mounted on the first support column by bolts, and a connecting piece connecting the sleeve and the corresponding side wall surface of the material storage tank.

[0027] Preferably, the material distribution conveyor further comprises a leveling mechanism provided on the bracket and located on both sides of the conveying assembly; the leveling mechanism is located behind the material storage tank;

[0028] The leveling mechanism includes a second support column vertically arranged on the bracket, a horizontal support rod horizontally arranged on the second support column, and a circular pressure plate rotatably arranged around the axis of the horizontal support rod; the bottom of the circular pressure plate contacts the top of the conveying assembly.

[0029] The beneficial effects are:

[0030] 1. In the polyester fabric coating production device of the present invention, a scraper rotates under the drive of a debris removal conveyor, scraping away impurities such as dried paint from the front, rear, and side inner walls. It also filters impurities, such as dried paint or fabric debris, from the reservoir, eliminating the accumulation of impurities at the bottom of the reservoir. This ensures a uniform distance between the discharge port and the fabric, resulting in a uniform coating thickness and ensuring fabric quality. Furthermore, the scraper's rotation within the reservoir accelerates the flow of the paint, preventing it from drying out.

[0031] 2. By setting up two scrapers, problems such as the scraper being too long, the movement resistance being too large when rotating in the paint, and the scraper being easily bent or deformed can be avoided when using only one scraper. In addition, since the two scrapers have overlapping areas when scraping impurities, the scraping effect of impurities is better and no areas are missed.

[0032] 3. When the scraper is scraping off firmly adhering impurities, the scraper can rotate relative to the strip mounting seat, that is, the scraper is in flexible contact with the impurities, so that the scraper can continue to rotate under the drive of the endless conveyor belt, avoiding damage to the scraper and the driving mechanism of the impurity removal conveyor.

[0033] 4. When the scraper rotates to the bottom of the storage tank, the side end of the scraper deflects toward the feeding position, which facilitates the paint in the middle of the storage tank to flow to the side end, thereby allowing the paint to quickly fill the storage tank, thereby facilitating the coating work of the fabric.

[0034] 5. The storage curved plate can scrape off the impurities adhering to the scraper and play the role of temporarily storing impurities. As the circular rotating disk rotates continuously, the storage curved plate vibrates back and forth along the width of the fabric, thereby accelerating the downward flow of the paint in the storage curved plate.

[0035] 6. By setting a rotating roller, when the cloth passes through the front end of the discharge port, the rotating roller is driven to rotate, so that the paint at this location is in a flowing state, thereby preventing the paint from drying up. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0058] Example 1 of the polyester fabric production coating device provided by the present invention:

[0059] The polyester fabric production coating device of the present invention is used to perform coating treatment on polyester fabrics, for example, coating the surface of polyester fabrics with polyurethane, fluorocarbon, acrylic acid, etc., and can coat and modify the surface of polyester fabrics to achieve sun protection, waterproof, antibacterial and other effects. Figures 1 to 13 As shown, the polyester fabric coating device of the present invention includes a fabric conveyor, a reservoir 2 for storing coating material spaced above the fabric conveyor, a debris removal conveyor 3 within the reservoir 2, a scraper assembly 4, and a debris storage curved plate 5. A discharge port is provided at the bottom of the reservoir 2 for coating the coating material to flow out for application to the fabric surface.

[0060] like Figure 1 As shown, the fabric conveyor includes a support 11 and a conveying assembly 12 mounted on the support 11 for conveying fabric. The fabric conveyor can be a belt conveyor. The conveying assembly 12 includes a driving wheel, a driven wheel, an endless belt fitted over the driving and driven wheels, and a drive mechanism, such as a fabric drive motor, for rotating the driving wheel. During operation, fabric is placed on the endless belt and passed through the gap between the endless belt and the material reservoir 2. Paint is then injected into the reservoir 2. The paint flows out through the outlet at the bottom of the reservoir 2 and adheres to the fabric. Driven by the endless belt, the coated fabric moves forward, ultimately forming a coated fabric.

[0061] like Figure 1 、 Figure 2 As shown, the material distribution conveyor also includes an adjustable support mechanism 13 provided on the bracket 11 and located on both sides of the conveying assembly 12. The adjustable support mechanism 13 includes a first support column 131 vertically provided on the bracket 11, a sleeve 132 adjustable up and down on the first support column 131 by bolts, and a connector 133 connecting the sleeve 132 and the corresponding side wall surface of the storage tank 2. The connector 133 includes a connecting column and a clamping block for clamping the top edge of the storage tank 2. The clamping block has a clamping opening with an opening facing downward for clamping the top edge of the storage tank 2. In order to improve the firmness of the connection, a bolt connector 133 may also be provided at the clamping block and the top edge of the storage tank 2.

[0062] The thickness of the coating on the fabric is determined by the distance between the bottom of the reservoir 2 and the top surface of the fabric conveyor. A larger distance means more coating material flows out, resulting in a thicker coating. In the present invention, an adjustable support mechanism 13 is provided to adjust the distance between the reservoir 2 and the fabric conveyor, thereby adjusting the coating thickness on the fabric, adapting to different fabric production requirements. During operation, the height of the reservoir 2 is adjusted by loosening the bolts and adjusting the position of the sleeve 132 and connector 133 up and down. Once the height is adjusted, the bolts are tightened to complete the adjustment of the reservoir 2, thereby adjusting the coating thickness of the fabric.

[0063] like Figure 1As shown, the fabric conveyor further includes a leveling mechanism 14 mounted on the support 11 and located on both sides of the conveying assembly 12. The leveling mechanism 14 is located in front of the material storage tank 2. In the present invention, the direction of fabric conveyance is referred to as the front, and the direction opposite to the fabric conveyance direction is referred to as the rear. The width of the conveying assembly 12 is the width of the fabric. The leveling mechanism 14 includes a second support column 141 vertically mounted on the support 11, a horizontal support rod horizontally mounted on the second support column 141, and a circular pressure plate 142 rotatably mounted around the axis of the horizontal support rod. The bottom of the circular pressure plate 142 contacts the top of the conveying assembly 12. Specifically, the bottom of the circular pressure plate 142 contacts the top of the endless belt of the conveying assembly 12. This contact creates a certain pressure between the circular pressure plate 142 and the endless belt of the conveying assembly 12.

[0064] In the present invention, the conveying component 12 is started, causing the endless belt to rotate, driving the circular pressure plate 142 to rotate, thereby pressing and leveling the endless belt, ensuring that the cloth does not have wrinkles on the endless belt, ensuring the flatness of the cloth, and thereby improving the coating quality of the cloth.

[0065] like Figure 4 As shown, the reservoir 2 has openings at both the top and bottom. The top opening is used to inject paint. The bottom opening serves as the aforementioned discharge port. The reservoir 2 comprises a front inner wall 21 and a rear inner wall 22, arranged sequentially along the fabric's conveying direction. Two side inner walls 23, arranged sequentially along the fabric's width and connecting the front and rear inner walls 21 and 22, are also included. Both the front and rear inner walls 21 and 22 have concave curved surfaces. The space formed by these two curved surfaces and the two side inner walls 23 serves as the paint storage space.

[0066] like Figure 4 As shown, the dust removal conveyor 3 comprises two rollers 31 positioned between two curved surfaces and an endless conveyor belt 32 mounted on the rollers 31. The horizontal conveying direction of the endless conveyor belt 32 is parallel to the conveying direction of the fabric. The axes of the two rollers 31 extend along the width of the fabric, and the length of the rollers 31 is equal to or slightly less than the distance between the two side inner walls 23 of the storage tank 2, facilitating rotation of the rollers 31 and the endless conveyor belt 32. The two rollers 31 are rotatably mounted on the side inner walls 23 of the storage tank 2. The two rollers 31 include a driving roller and a driven roller. The dust removal conveyor 3 can also be a belt conveyor. The dust removal conveyor 3 also includes a dust removal drive motor 33 for driving the driving rollers. The dust removal drive motor 33 can be mounted on the outer wall of the storage tank 2, on the first support column 131, or on the bracket 11 via a support structure.

[0067] like Figures 1 to 11As shown, the scraper assembly 4 includes a scraper 41 mounted on the endless conveyor belt 32 and rotatable about an axis in the width direction of the fabric. The scraper 41 is driven by the endless conveyor belt 32 to rotate synchronously to scrape impurities from the front inner wall 21, the rear inner wall 22, and the side inner walls 23. Specifically, the scraper 41 is in the form of an elongated flat plate with mesh holes formed therein. The scraper 41 extends along the width direction of the fabric. The side of the scraper 41 facing away from the endless conveyor belt 32 is configured to contact the curved surface of the front inner wall 21 or the rear inner wall 22. At least one side of the scraper 41 contacts the corresponding side inner wall 23. When the scraper 41 moves to the bottom of the storage tank 2, a gap is formed between the scraper 41 and the fabric, meaning that the scraper 41 does not contact the fabric.

[0068] In the present invention, the impurity removal conveyor 3 is activated, causing the endless conveyor belt 32 to rotate, driving the scraper 41 on the endless conveyor belt 32 to rotate synchronously. The scraper 41 can scrape off impurities such as dried paint on the front inner wall 21, the rear inner wall 22, and the side inner wall 23, and can filter impurities in the storage tank 2, such as dried paint or fabric debris, which adhere to the scraper 41 and are finally stored in the storage bent plate 5. This prevents impurities from accumulating at the bottom of the storage tank 2, thereby ensuring that the distance between the discharge port and the fabric is equal, thereby making the coating thickness of the fabric uniform and ensuring the fabric forming quality. Moreover, the scraper 41 is arranged to rotate in the storage tank 2, which also accelerates the flow of the paint and prevents the paint from drying out.

[0069] like Figure 4 and Figure 8 As shown, there are two scraper assemblies 4. The two scraper assemblies 4 are centrally symmetrical about the center of the endless conveyor belt 32. Along the width of the fabric, one end of the scraper 41 contacts the side inner wall 23, while the other end of the scraper 41 extends beyond the center of the storage tank 2. This arrangement ensures that the two scrapers 41 scrape impurities in the storage tank 2 in an overlapping area.

[0070] In the present application, two scraper assemblies 4 are provided, so that there are also two scrapers 41, each scraper 41 is used to scrape impurities from the inner wall of one side of the storage tank 2, thereby avoiding the problems of the scraper 41 being too long when only one scraper 41 is used, resulting in excessive movement resistance when rotating in the paint, and the scraper 41 being easily bent or deformed. Moreover, since the two scrapers 41 have overlapping areas for scraping impurities, the scraping effect of impurities is improved, and areas that are not scraped are prevented.

[0071] like Figure 9 and Figure 11As shown, the scraper assembly 4 also includes a strip-shaped mounting base 42 disposed on the outer surface of the endless conveyor belt 32 along the width of the fabric. A scraper 41 is mounted on the strip-shaped mounting base 42, pivoting along its length. A first rotating shaft is provided at the end of the scraper 41, adapted to engage with a first rotating groove at the end of the strip-shaped mounting base 42. A first torsion spring is mounted on the first rotating shaft, securing the scraper 41 to its original position. The first torsion spring's ends are connected to the scraper 41 and the strip-shaped mounting base 42, respectively.

[0072] When the scraper 41 is driven by the endless conveyor belt 32 to remove impurities, if some dried-up paint adheres firmly to the inner wall of the storage tank 2, the scraper 41 and the impurities will be in rigid contact, potentially damaging the scraper 41 and the drive mechanism of the impurity removal conveyor 3. In contrast, in the present invention, when the scraper 41 is scraping the firmly adhered impurities, the scraper 41 can rotate relative to the strip mounting base 42. That is, the scraper 41 and the impurities are in flexible contact, allowing the scraper 41 to continue rotating under the drive of the endless conveyor belt 32, thus avoiding damage to the scraper 41 and the drive mechanism of the impurity removal conveyor 3. When the scraper assembly 4 leaves the location of the firmly adhered impurities, the scraper 41 rotates in the opposite direction relative to the strip mounting base 42 under the reset action of the first torsion spring, achieving reset and resuming the scraping operation.

[0073] Moreover, the scraper assembly 4 moves to the debris storage bent plate 5 driven by the annular conveyor belt 32, and the scraper 41 rotates relative to the strip mounting seat 42 under the obstruction of the debris storage bent plate 5. The debris storage bent plate 5 can also scrape off impurities adhered to the scraper 41. When the scraper assembly 4 leaves the position of the debris storage bent plate 5, the scraper 41 rotates in the opposite direction relative to the strip mounting seat 42 under the reset action of the first torsion spring, achieves reset, and continues the scraping work.

[0074] like Figures 9 to 13 As shown, the scraper assembly 4 also includes a limiting groove opened on the outer surface of the endless conveyor belt 32 and extending to the middle of the endless conveyor belt 32 along the width direction of the cloth, and a push rod 43 assembled in the limiting groove. The end of the strip mounting seat 42 away from the side inner wall 23 rotates around an axis perpendicular to the surface of the endless conveyor belt 32 and is connected to the end of the push rod 43 located in the middle of the endless conveyor belt 32. The corresponding end of the push rod 43 is provided with a second rotating shaft 44 for cooperating with the second rotating groove at the end of the strip mounting seat 42. A second torsion spring for resetting the strip mounting seat 42 is sleeved on the second rotating shaft 44, and the two ends of the second torsion spring are respectively connected to the push rod 43 and the strip mounting seat 42. The axis of the second rotating shaft 44 is eccentrically arranged at the rotating end of the strip mounting seat 42. Specifically, the axis of the second rotating shaft 44 is arranged on the side of the rotating end of the strip mounting seat 42 away from the feeding position, as shown in FIG. Figure 11 and Figure 12As shown. The scraper 41 contacts one end of the side inner wall 23 and is provided with a rounded corner 411 at the corner away from the feeding position. The end of the push rod 43 located on the side of the annular conveyor belt 32 is inserted into the annular groove on the corresponding side inner wall 23, and the groove depth at the bottom position of the annular groove is less than the groove depth at the rest of the annular groove. Specifically, a rotating seat 24 is provided on the side inner wall 23, and two rollers 31 are rotatably set on the rotating seat 24, and the rotating seat 24 is provided with an annular groove. The bottom position of the annular groove is a shallow groove 241, and the rest of the annular groove is a deep groove 242, and the bottom wall of the deep groove 242 is connected to the bottom wall of the shallow groove 241 by a first guide slope.

[0075] The paint in the storage tank 2 is mainly stored between the impurity removal conveyor 3 and the material distribution conveyor, and the feeding position is located in the middle position above the rear end of the storage tank 2. Due to the poor fluidity of the paint, the paint is not easy to flow and diffuse to both sides of the storage tank 2 after falling into the middle of the storage tank 2 from the feeding position, which is not conducive to the coating work of the material distribution.

[0076] In the present invention, when the endless conveyor belt 32 drives the scraper assembly 4 to move to the top and front and rear ends of the storage tank 2, the push rod 43 is inserted into the deep groove 242, and the scraper 41 extends along the width direction of the cloth. When the endless conveyor belt 32 drives the scraper assembly 4 to the bottom of the reservoir 2, the push rod 43 slides from the deep groove 242 into the shallow groove 241, pushing the strip mounting seat 42 and the scraper 41 toward the corresponding side inner wall 23. Because the strip mounting seat 42 and the scraper 41 are in contact with the side inner wall 23, and because the strip mounting seat 42 is eccentrically arranged, the corresponding end of the scraper 41 is provided with a rounded corner 411 away from the feeding position. As a result, the strip mounting seat 42 is subjected to a force near the feeding position under the thrust of the push rod 43, causing the scraper 41 to deflect relative to the push rod 43. The deflection direction is close to the feeding position, that is, the length direction of the scraper 41 forms a certain deflection angle with the width direction of the cloth. The side end of the scraper 41 deflects toward the feeding position, facilitating the flow of paint from the middle of the reservoir 2 to the side end, thereby quickly filling the reservoir 2 with paint, thereby facilitating the coating of the cloth.

[0077] like Figures 1 to 4 As shown, the garbage storage curved plate 5 is a concave arc-shaped plate and is located between the rear inner wall 22 and the endless conveyor belt 32 along the width direction of the cloth. It is used to scrape and receive impurities adhering to the scraper 41. Specifically, the garbage storage curved plate 5 is located on the rear inner wall 22. The garbage storage curved plate 5 is provided with mesh holes.

[0078] In the present invention, the curved plate-shaped impurity storage bent plate 5 can scrape off impurities adhering to the scraper 41 and store the impurities, and the paint can flow into the storage tank 2 through the mesh of the impurity storage bent plate 5. By providing the impurity storage bent plate 5, it is convenient to scrape and centrally store impurities on the scraper 41, which is convenient for subsequent cleaning work.

[0079] In other embodiments, the debris storage bent plate 5 is rotatably mounted on the rear inner wall 22 via a third rotating shaft, and a third torsion spring is mounted on the third rotating shaft to reposition the debris storage bent plate 5. When the scraper 41 rotates to contact the debris storage bent plate 5, the debris storage bent plate 5 can rotate a certain angle relative to the rear inner wall 22, thereby scraping off impurities adhering to the scraper 41 while not hindering the scraper 41 from continuing to rotate.

[0080] like Figure 5 and Figure 6 As shown, the end of the storage bent plate 5 away from the debris removal drive motor 33 is installed on the corresponding side inner wall 23 through a spring 51, and the end of the storage bent plate 5 close to the debris removal drive motor 33 is provided with a connecting rod 52 that passes through the corresponding side inner wall 23. A circular rotating disk 53 is fixedly sleeved on the output shaft of the debris removal drive motor 33. The end surface of the circular rotating disk 53 close to the storage bent plate 5 is provided with grooves 531 uniformly distributed along the circumference of the circular rotating disk 53. A second guiding inclined surface is provided between the bottom wall of the groove 531 and the end surface of the circular rotating disk 53. The end of the connecting rod 52 away from the storage bent plate 5 is in contact with the corresponding end surface of the circular rotating disk 53.

[0081] In the present invention, the impurity removal drive motor 33 rotates, driving the circular rotating disk 53 to rotate. The circular rotating disk 53 contacts and cooperates with the connecting rod 52. When the connecting rod 52 is inserted into the groove 531, the impurity storage curved plate 5 moves toward the circular rotating disk 53 under the elastic force of the spring 51. When the connecting rod 52 disengages from the groove 531 and contacts the end surface of the impurity storage curved plate 5, the impurity storage curved plate 5 moves away from the circular rotating disk 53 under the push of the connecting rod 52. Therefore, as the circular rotating disk 53 continues to rotate, the impurity storage curved plate 5 vibrates back and forth along the width of the fabric, thereby accelerating the downward flow of the paint in the impurity storage curved plate 5.

[0082] like Figures 2 to 5 As shown, the polyester fabric coating production device also includes a feed pipe 8, the outlet of the feed pipe 8 is arranged above the storage bent plate 5. A piece of cloth strip can be wrapped around the outlet of the feed pipe 8 so that the paint can flow evenly, and the cloth strip can expand the range of the discharge port to avoid paint accumulation.

[0083] In the present invention, the paint is transported through the feed pipe 8 and flows from the outlet of the feed pipe 8 to the top of the storage bent plate 5, which can filter the paint. The reciprocating shaking of the storage bent plate 5 also facilitates the rapid fall of the paint.

[0084] like Figure 4As shown, a rotating roller 6 is provided at the bottom front end of the discharge port, along the direction of fabric delivery, for rotation driven by the fabric. In the present invention, the coated fabric is discharged through the front end of the discharge port. To prevent the coating from drying out at the front end of the discharge port, which could affect the coating quality, rotating roller 6 is provided. As the fabric passes through the front end of the discharge port, it drives rotating roller 6 to rotate, keeping the coating in this area fluid and preventing it from drying out.

[0085] like Figure 1 As shown, the polyester fabric coating production apparatus further includes a drying mechanism 7 located at the rear end of the fabric conveyor. Drying mechanism 7 is used to dry the coated fabric. Drying mechanism 7 defines a drying chamber extending along the fabric conveyor direction, through which the fabric conveyor passes. Drying mechanism 7 may include a heating assembly and a blowing assembly. The heating assembly generates heat, while the blowing assembly directs the heat toward the fabric. The heating assembly may be a heating wire or a heating tube, and the blowing assembly may be a fan.

[0086] In the present invention, the cloth coated with paint is conveyed to the drying chamber of the drying mechanism 7 by the cloth conveyor, so that the paint can be dried quickly, thereby ensuring the coating quality of the cloth and accelerating the production efficiency of the coated cloth.

[0087] The overall working process of the present invention is as follows:

[0088] The coating process of the cloth: the conveying component 12 of the cloth conveyor conveys the cloth forward, and the cloth adheres to the paint in the storage tank 2 and is output from the front end of the storage tank 2. Finally, it is dried by the drying mechanism 7 to form a finished product.

[0089] Impurity Removal Process: While the coating is being applied, the impurity removal conveyor 3 is activated, rotating the endless conveyor belt 32 and driving the scraper 41 on it to rotate synchronously. When the scraper 41 reaches the bottom of the reservoir 2, the push rod 43 slides from the deep groove 242 into the shallow groove 241. The push rod 43 pushes the strip mounting base 42 and the scraper 41 toward the corresponding side inner wall 23. The push force of the push rod 43 causes the strip mounting base 42 to deflect the scraper 41 relative to the push rod 43 toward the feed position, facilitating the flow of paint from the center of the reservoir 2 toward the sides, thereby rapidly filling the reservoir 2. When at the bottom of the reservoir 2, the scraper 41 can scrape impurities from the inner wall of the reservoir 2. When the scraper 41 leaves the bottom of the material storage tank 2, the push rod 43 slides from the shallow groove 241 into the deep groove 242. The strip mounting seat 42 and the scraper 41 are reset under the action of the second torsion spring. The length direction of the strip mounting seat 42 and the scraper 41 is parallel to the width direction of the material. Driven by the endless conveyor belt 32, the scraper 41 can successively scrape impurities from the front inner wall 21 and the rear inner wall 22. When the scraper 41 rotates to the rear inner wall 22 and contacts the storage curved plate 5, the scraper 41 rotates relative to the strip mounting seat 42 under the obstruction of the storage curved plate 5, scraping impurities adhering to the scraper 41. The scraper 41 continues to rotate. When the scraper 41 leaves the storage curved plate 5, the scraper 41 is reset under the action of the first torsion spring and continues to scrape until the scraper 41 rotates to the bottom of the material storage tank 2 again. The scraper 41 rotates cyclically to continuously scrape away impurities on the front inner wall 21 , the rear inner wall 22 and the side inner walls 23 .
